Why Make This Recipe
Choosing to make gluten-free lemon blueberry bars offers several benefits. For those with gluten sensitivities or celiac disease, finding delicious desserts can be challenging. This recipe ensures that you can indulge without worry. Additionally, the use of fresh blueberries provides a range of nutritional benefits. Blueberries are low in calories and rich in nutrients such as antioxidants, vitamins C and K, and fiber.
The balance of tart lemon juice and sweet blueberries makes these bars a refreshing option for warmer months. They also showcase the versatility of gluten-free baking, allowing anyone to enjoy delicious treats without compromising their dietary restrictions.
How to Prepare Gluten-Free Lemon Blueberry Bars
Step 1: Preheat the Oven and Prepare the Baking Pan
Begin by preheating your oven to 350ºF (175ºC). This ensures that the bars bake evenly. While the oven heats, prepare an 8×8-inch baking pan. Use non-stick spray to coat the pan lightly. For added assurance that your bars won’t stick, line the pan with two pieces of parchment paper crisscrossed. Making a sling with the paper allows for easy removal of the bars after baking.
Step 2: Make the Crust
In a stand mixer or a large mixing bowl with an electric mixer, combine ¾ cup (150g) granulated sugar with 2 tablespoons of lemon zest. The lemon zest adds a bright flavor that enhances the taste of the entire dessert. Beat the mixture on high speed for about 1 minute. This step infuses the sugar with the aromatic oils from the lemon zest.
Next, add 1 cup (227g) of room-temperature salted butter and 1 teaspoon of vanilla extract. Mix this combination on high for 2-3 minutes until light and fluffy. The fluffy texture is important as it will give your bars a tender crumb.
Gradually add 2 ⅓ cups (280g) of gluten-free 1:1 baking blend and ½ teaspoon of fine sea salt. Mix on low speed until a crumbly dough forms. If the mixture feels too dry, you can add a small splash of water or milk to help bring it together.
Step 3: Press the Dough into the Pan
Once your dough is ready, divide it into two portions. Take about ⅔ of the dough and press it evenly into the bottom of the prepared pan. This will serve as the shortbread base for your bars. Use your fingers or a spatula to create an even layer, making sure it reaches the corners of the pan.
Step 4: Prepare the Blueberry Filling
In a small bowl, combine 3 cups (444g) of fresh blueberries, ¼ cup (50g) of granulated sugar, 2 tablespoons (30ml) of lemon juice, and 1 tablespoon (8g) of cornstarch. The sugar helps to draw out the juices from the blueberries, while the cornstarch acts as a thickener for the filling. Gently toss the blueberries until they are coated. Be careful when mixing to not crush the berries.
Step 5: Assemble and Bake
Carefully spoon the blueberry mixture over the shortbread base in the pan. Spread the blueberries out evenly so they are well-distributed. Next, crumble the remaining dough over the blueberries. This will create a crisp topping that contrasts nicely with the soft blueberries.
Bake the bars in the preheated oven for about 60 minutes or until the top is lightly golden. Keep an eye on them in the last few minutes to ensure they don’t over-bake. Allow the bars to cool completely in the pan. This is crucial as they will firm up as they cool, making them easier to cut.
Step 6: Prepare the Glaze
While the bars cool, prepare a simple glaze by mixing ¼ cup (30g) of powdered sugar with ½ tablespoon of lemon juice in a small bowl. Adjust the consistency by adding more sugar for thickness or more lemon juice for a thinner glaze. Once the bars are fully cooled, drizzle the glaze over the top for an elegant finish.
Step 7: Cut and Serve
Using the parchment paper, lift the cooled bars out of the pan and cut them into squares. Clean your knife between cuts for neat edges.

How to Store Gluten-Free Lemon Blueberry Bars
Proper storage is essential to keep your bars as fresh as possible. Here are some storage tips:
Refrigerator: Store the bars in an airtight container in the refrigerator for up to 5 days. This helps maintain freshness and prevents them from drying out.

Tips for Mastering Gluten-Free Lemon Blueberry Bars
Making gluten-free dessert can sometimes be tricky, so here are some tips to ensure success:
Quality Gluten-Free Flour: Not all gluten-free flour blends are created equal. Choose a high-quality 1:1 baking blend that includes xanthan gum for the best results.
Room Temperature Ingredients: Always use room-temperature butter and eggs. This promotes a smoother batter and helps the ingredients blend better.
Evenly Distribute the Blueberries: Make sure the blueberry filling is evenly spread; this prevents any overly soggy areas.
Bake Until Just Golden: Keep an eye on the bars while baking. Remove them once the edges are golden to avoid dry, overcooked bars.
Glaze Application: Drizzle the glaze after the bars have completely cooled to ensure it doesn’t melt or drip off. A squeeze bottle can help create a beautiful pattern.
Variations
There are numerous ways to customize this recipe. Here are a few ideas:
Fruits: Swap blueberries for other berries like raspberries or strawberries, or a mix of different fruits.
Flavor Additions: Experiment with adding lavender or almond extract for a unique twist.
Nut Topping: Add chopped walnuts or almonds to the crumble topping for extra texture and flavor.
Coconut: Stir in some toasted coconut flakes into the filling or topping for additional flavor and chewiness.
Seasonal Ingredients: In the fall, you might consider adding apples or cranberries instead of blueberries.
